To investigate whether patients with ankylosing spondylitis have poorer balance than normal subjects, and to study the relationship between balance and posture.
Balance was studied in 30 ankylosing spondylitis subjects using sway magnetometry, making quantitative measurements of movement at the hips with eyes open and eyes closed. The results were compared with data from 58 normal subjects. Balance was also compared with quantitative measurements of posture.
The numbers of patients with poor balance, above the 95th percentile for normal, were significantly greater than expected; 18% for eyes open (P = 0. 03) and 23% for eyes closed (P = 0.004). No significant relationships between balance and any of the quantitative descriptions of posture were demonstrated.
A significant proportion of ankylosing spondylitis patients have poorer balance than normal subjects.
调查强直性脊柱炎患者的平衡能力是否比正常受试者差，并研究平衡与姿势之间的关系。
使用摇摆磁力测定法对30名强直性脊柱炎受试者的平衡能力进行研究，分别在睁眼和闭眼状态下对髋部运动进行定量测量。将结果与58名正常受试者的数据进行比较。还将平衡能力与姿势的定量测量结果进行了比较。
平衡能力较差（高于正常水平第95百分位数）的患者数量显著多于预期；睁眼时为18%（P = 0.03），闭眼时为23%（P = 0.004）。未发现平衡能力与任何姿势定量描述之间存在显著关系。
相当一部分强直性脊柱炎患者的平衡能力比正常受试者差。
